Internal server error while publishing pbix file.

Hi folks,


I created a custom connector and implemented an incremental refresh in that. I defined the RangeStart and RangeEnd parameters and did the required settings. When I try to publish it, I receive an internal server 500 error. I traced the error using fiddler and got this:



Could someone please help me resolve my issue? I am really stuck here and the error message here doesn't seem to help much.

Hi @cte_crest ,


Today I also got this error and I resolved it by removing the workspace from the capacity.


It seems my workspace is tied up with A1 capacity which was some reason stopped due to that i got this error.

Hi @cte_crest 


Do you publish .pbix file to PBI Report Server or Power BI Service?


If it is the former, does your account have a Power BI Pro license?


If it is the latter, please log on Power Bi service, upload your pbix files via Get Data -> Files -> Local file to check whether they can be published successfully.


If still not help, you'd better create a support ticket in Power BI Support to get further assitant.

It's the latter one, i.e., Power BI service.


But, I am using an incremental refresh, and I think it would not be useful if I upload the pbix file manually. I tried with other types of pbix file, they are being published without any error. 

Hi @cte_crest 


To investigate further, please follow the steps below:

  1. Check the temp folder, C:\Users\User name\AppData\Local\Power BI, find the latest file after reproduce the issue and open it with notepad;
  2. Enable Tracing under Power BI Desktop File->Options and settings->Options->GLOBAL->Diagnostics, select Enable Tracing;
  3. Generate a Fiddler trace. (Fiddler Web Debugger Tool)

If available, upload them into OneDrive and post the shared link here. We will help to take a look.

In addition, try to take a reinstall or a repair of the Power BI desktop, see if this would make any difference.

Thanks for the help.

I couldn't find Power BI at this location: C:\Users\User name\AppData\Local\Power BI.


However, I have followed the steps and have attached the fiddler trace here:


Please have a look at it. Appreciate for the help!
